* shutdown: allow graceful shutdown for SIGTERM on posix

The signal is already trapped; make it do the same thing as SIGQUIT to
be more inline with Unix/Linux shutdown expectations.

Fixes #1993

* Implement comment feedback ideas

* Turn on KeepAlive in QuicConfig of RoundTripper

* Update reverseproxy.go

* caddymain: fix setCPU silently ignoring small percent values

the percent value is resolved in a GOMAXPROCS relative number by simple
division, thus rounding down the non-integer quotient. If zero, the call
to runtime.GOMAXPROCS is silently ignored.

We decide here to exceptionally round up the CPU cap in case of percent
values that are too small.

* caddymain: gofmt -s

* Update README.md

I believe the owner and group of the `chown` command here are mixed up. As it was caused a permissions issue, with the service being unable to read the directory.

Revert changes back to the original suggested changes

* First working mask

* IP Mask working with defaults and empty

* add tests for ipmask

* Store Mask as setup, some tidying, cleaner flow

* Prevent mask from running when directive not present

* use custom replacement to store masked ip

Caddyfile snippets

This allows custom replacements to be defined in a way that propagates
throughout all plugins.

* Checking that a server listener is not nil before printing verbose information

* Improved readability of a loop

* Simplify parseUpstream function

* Add SRV support for proxy upstream

This adds the ask sub-directive to tls that defines the URL of a backend HTTP service to be queried during the TLS handshake to determine if an on-demand TLS certificate should be acquired for incoming hostnames. When the ask sub-directive is defined, Caddy will query the URL for permission to acquire a cert by making a HTTP GET request to the URL including the requested domain in the query string. If the backend service returns a 2xx response Caddy will acquire a cert. Any other response code (including 3xx redirects) are be considered a rejection and the certificate will not be acquired.

* Update build instruction

This changes add proper an easy instruction for building.

* Update README.md

The rc.subr framework already takes care of substituting user. So, using
daemon's -u option is double user-substitution and fails if $caddy_user
is non-root.

caddy.go:569: could be simplified

sigtrap_posix.go:87: value of inst is never used

upgrade.go:151: should omit nil check; len() for nil slices is defined as zero
